Summary: The aquaculture industry has faced financial losses due to disease outbreaks, particularly in the Macrobrachium rosenbergii aquaculture industry. Understanding the host's defense mechanism is crucial for providing effective defense measures. This study used RNA-seq technology to investigate the immune pathways and genes related to innate immunity in hemocytes from M. rosenbergii. The results identified differentially expressed genes and revealed their involvement in antibacterial activities against gram-positive bacteria. These findings contribute valuable data for disease prevention and provide a basis for improved prevention strategies.

Summary: This paper discusses the importance of using probiotics for disease control in the high-yielding prawn variety, Macrobrachium rosenbergii. Intensive culture systems can lead to disease outbreaks, and probiotics have emerged as a promising alternative for disease control by enhancing the prawns' immunity and antagonizing pathogenic microorganisms.

Summary: The study reveals the important role of MrcMnSOD in antioxidant defense and antibacterial immune response in M. rosenbergii. Knocking down MrcMnSOD in vivo results in higher mortality rate and more residual bacteria, while an in vitro bacterial agglutination assay showed broad bacterial agglutination capabilities of MrcMnSOD.

Summary: The cytokine Astakine, identified in the freshwater prawn Macrobrachium rosenbergii, plays an important role in promoting the proliferation and differentiation of hematopoietic stem cells and regulating immune responses. Knockdown of MrAst, the homolog of Astakine, increases susceptibility to bacterial and viral infections and affects the functionality and apoptosis of hemocytes.

Summary: This study analyzed the miRNA and mRNA transcriptome of the freshwater prawn Macrobrachium rosenbergii infected with the bacteria Aeromonas hydrophila. Differentially expressed miRNAs and mRNAs were identified, and their target genes were predicted. Enrichment analysis revealed multiple functional categories related to immunity, apoptosis, and autophagy. During infection, a complex regulatory network involving key miRNAs and genes associated with immune and autophagy pathways was formed.

Summary: Toll-like receptors are a family of membrane receptors involved in innate immune responses. Two Toll-like receptors, MrToll1 and MrToll2, were identified in the giant freshwater prawn. They are constitutively expressed in various tissues and play essential roles in regulating immune-related gene expression.

Summary: Outbreaks of infectious disease in shrimp pose a serious threat to shrimp agriculture worldwide. Shrimp lack adaptive immunity and rely solely on innate immunity for defense against infectious disease. Toll-like receptors play a critical role in the shrimp innate immune system, with the identification of a new Toll-like receptor gene (MnToll) in Macrobrachium nipponense potentially involved in defense against WSSV.

Summary: Bursicon is a neuropeptide hormone in insects that regulates cuticle tanning and wing development, and also regulates the secretion of antimicrobial peptides. This study identified Mnburs alpha and Mnburs beta in Macrobrachium nipponense, showing their widespread expression in immune tissues and their upregulation in response to pathogen invasion. Knockdown and recombinant protein experiments suggest that Mnburs alpha and Mnburs beta play positive roles in AMP synthesis, with a mechanism involving the transcription factor Relish in innate immunity.

Summary: This study investigated the function of the PI3K-Akt signaling pathway in antibacterial immunity. The results showed that PI3K, AKT, and FoxO were highly expressed in the intestinal, hemocytes, and hepatopancreas. The expression levels of these factors were regulated by different pathogens. V. parahaemolyticus infection regulated the levels of PI3K, AKT, and FoxO more rapidly in hemocytes and the intestine, while S. aureus infection regulated the levels of these factors more rapidly in the hepatopancreas and gills. Additionally, the infections caused changes in the gene expression level of crustin, caspase 3, and NF-kappa B.
